Cotton variety fm 1953gltp

ABSTRACT

The cotton variety FM 1953GLTP is disclosed. The invention relates to seeds, plants, plant cells, plant tissue, harvested products and cotton lint as well as to hybrid cotton plants and seeds obtained by repeatedly crossing plants of variety FM 1953GLTP with other plants. The invention also relates to plants and varieties produced by the method of essential derivation from plants of FM 1953GLTP and to plants of FM 1953GLTP reproduced by vegetative methods, including but not limited to tissue culture of regenerable cells or tissue from FM 1953 GLTP.

FIELD OF THE INVENTION

This invention relates to the field of plant breeding. Moreparticularly, the invention relates to a variety of cotton designated asFM 1953GLTP, its essentially derived varieties and the hybrid varietiesobtained by crossing FM 1953GLTP as a parent line with plants of othervarieties or parent lines.

BACKGROUND OF THE INVENTION

Cotton is an important, fiber producing crop. Due to the importance ofcotton to the textile industry, cotton breeders are increasingly seekingto obtain healthy, good yielding crops of excellent quality.

Cotton is commonly reproduced by self-pollination and fertilization.This type of sexual reproduction facilitates the preservation of plantand variety characteristics during breeding and seed production. Thepreservation of these characteristics is often important to plantbreeders for producing cotton plants having desired traits. Othermethods of producing cotton plants having desired traits are also usedand include methods such as genetic transformation via Agrobacteriuminfection or direct transfer by microparticle bombardment. Examples ofsuch methods are disclosed, for example, in U.S. Pub. No. 20090049564,incorporated by reference herein in its entirety.

Due to the environment, the complexity of the structure of genes andlocation of a gene in the genome, among other factors, it is difficultto predict the phenotypic expression of a particular genotype. Inaddition, a plant breeder may only apply his skills on the phenotype andnot, or in a very limited way, on the level of the genotype. As aresult, a particular plant breeder cannot breed the same variety twiceusing the same parents and the same methodology. Thus, a newly bredvariety is an unexpected result of the breeding process. Indeed, eachvariety contains a unique combination of characteristics.

By carefully choosing the breeding parents, the breeding and selectionmethods, the testing layout and testing locations, the breeder may breeda particular variety type. In addition, a new variety may be tested inspecial comparative trials with other existing varieties in order todetermine whether the new variety meets the required expectations.

SUMMARY OF THE INVENTION

The invention relates to seeds, plants, plant cells, parts of plants,cotton lint or fiber, and cotton textiles of cotton variety FM 1953GLTPas well as to hybrid cotton plants and seeds obtained by repeatedlycrossing plants of FM 1953GLTP with other cotton plants, and EssentiallyDerived Varieties of cotton variety FM 1953GLTP. The inventionencompasses plants and plant varieties produced by the method ofderivation or essential derivation from plants of FM 1953GLTP and toplants of FM 1953GLTP reproduced by vegetative methods, including butnot limited to regeneration of embryogenic cells or tissue of FM1953GLTP. The invention also encompasses methods of producing cottonseeds that comprise crossing plants of cotton variety FM 1953GLTP eitherwith itself or with a second, distinct cotton plant.

DETAILED DESCRIPTION OF THE INVENTION

The invention has been obtained by a general breeding process comprisingthe steps outlined below. For reference, see chapter 11, “BreedingSelf-Pollinated Crops by Hybridization and Pedigree Selection” in Briggsand Knowles (1967).

Parent plants, which have been selected for good agronomic and fiberquality traits are manually crossed in different combinations. Theresulting F1 (Filial generation 1) plants are self fertilized and theresulting F2 generation plants, which show a large variability onaccount of optimal gene segregation, are planted in a selection field.

These F2 plants are observed during the growing season for health,growth vigor, plant type, plant structure, leaf type, stand ability,flowering, maturity, seed yield, boll type, boll distribution, bollsize, fiber yield and fiber quality. Plants are then selected. Theselected plants are harvested and the bolls analyzed for fibercharacteristics and the seed cleaned and stored. This procedure isrepeated in the following growing seasons, whereby the selection andtesting units increase from individual plants in the F2, to multipleplant containing ‘lines’ (descending from one mother plant) in the F5and the number of units decrease from approximately 2500 plants in theF2 to 20 lines in the F5 by selecting about 10-20% of the units in eachselection cycle.

The increased size of the units, whereby more seed per unit isavailable, allows the selection and testing in replicated trials on morethan one location with a different environment and a more extensive andaccurate analysis of the fiber quality.

The lines or candidate varieties become genotypically more homozygousand phenotypically more homogeneous by selecting similar plant typeswithin a line and by discarding the so called off-types from the veryvariable F2 generation on to the final F7 or F8 generation.

Depending on the intermediate results the plant breeder may decide tovary the procedure described above, such as by accelerating the processby testing a particular line earlier or retesting a line another year.He may also select plants for further crossing with existing parentplants or with other plants resulting from the current selectionprocedure.

By the method of recurrent backcrossing, as described by Briggs andKnowles, supra, in chapter 13, “The Backcross Method of Breeding”, thebreeder may introduce a specific trait or traits into an existingvaluable line or variety, while otherwise preserving the uniquecombination of characteristics of this line or variety. In this crossingmethod, the valuable parent is recurrently used to cross it at least twoor three times with each resulting backcross F1, followed by selectionof the recurrent parent plant type, until the phenotype of the resultingF1 is similar or almost identical to the phenotype of the recurrentparent with the addition of the expression of the desired trait ortraits.

This method of recurrent backcrossing eventually results in anessentially derived variety, which is predominantly derived from therecurrent parent or initial variety. This method can therefore also beused to get as close as possible to the genetic composition of anexisting successful variety. Thus, compared to the recurrent parent theessentially derived variety retains a distinctive trait, which can beany phenotypic trait, with the intention to profit from the qualities ofthat successful initial variety.

Depending on the number of backcrosses and the efficacy of the selectionof the recurrent parent plant type and genotype, which can be supportedby the use of molecular markers as described by P. Stam (2003), thegenetic conformity with the initial variety of the resulting essentiallyderived variety may vary between 90% and 100%. The relatedness can, forexample be determined by fingerprinting techniques (e.g., making use ofisozyme markers and/or molecular markers such as SNP markers, AFLPmarkers, microsatellites, minisatellites, RAPD markers, RFLP markers andothers). A plant is “closely related” to FM 1953GLTP if its DNAfingerprint is at least 80%, 90%, 95% or 98% identical to thefingerprint of FM 1953GLTP. In one embodiment, AFLP markers are used forDNA fingerprinting (Vos et al. 1995, Nucleic Acid Research 23:4407-4414). A closely related plant may have a Jaccard's Similarityindex of at least about 0.8, preferably at least about 0.9, 0.95, 0.98or more (Pisanu et al. ISHS 2004, Acta Hort. 660).

Other than recurrent backcrossing, as described herein, such essentiallyderived variety may also be obtained by the selection from an initialvariety of an induced or natural occurring mutant plant, or of anoccurring variant (off-type) plant, or of a somaclonal variant plant, orby genetic transformation of regenerable plant tissue or embryogeniccell cultures of the said initial variety by methods well known to thoseskilled in the art, such as Agrobacterium-mediated transformation asdescribed by Sakhanokho et al, (2004), Reynaerts et al. (2000), Umbecket al. (1988) and others. Examples of transgenic events transformed inthis way are “LLCotton25,” USDA-APHIS petition 02-042-01p, “Cot 102,”USDA-APHIS petition 03-155-01p, and “281-24-236,” USDA-APHIS petition03-036-01p combined with “3006-210-23,” USDA-APHIS petition 03-036-02p.Information regarding these and other transgenic events referred toherein may be found at the U.S. Department of Agriculture's (USDA)Animal and Plant Health Inspection Service (APHIS) website. An “Event”is defined as a (artificial) genetic locus that, as a result of geneticengineering, carries a foreign DNA comprising at least one copy of thegene(s) of interest. Other methods of genetic transformation are wellknown in the art such as microprojectile bombardment. See, e.g., U.S.Publication No. 20090049564, which is incorporated by reference hereinin its entirety.

The plants selected or transformed retain the unique combination of thecharacteristics of FM 1953GLTP, except for the characteristics (e.g.,one, two, three, four or five characteristics) changed by the selectionof the mutant or variant plant or by the addition of a desired trait viagenetic transformation. Therefore, the product of essential derivation(i.e., an essentially derived variety), has the phenotypiccharacteristics of the initial variety, except for the characteristicsthat change as a result of the act of derivation. Plants of theessentially derived variety can be used to repeat the process ofessential derivation. The result of this process is also a varietyessentially derived from said initial variety.

In one embodiment, FM 1953GLTP progeny plants are produced by crossingplants of FM 1953GLTP with other, different or distinct cotton plants,and further selfing or crossing these progeny plants with other,distinct plants and subsequent selection of derived progeny plants. Theprocess of crossing FM 1953GLTP derived progeny plants with itself orother distinct cotton plants and the subsequent selection in theresulting progenies can be repeated up to 7 or 8 times in order toproduce FM 1953GLTP derived cotton plants.

FM 1953GLTP was developed by a backcrossing breeding program utilizing aconventional proprietary line as the recurrent parent. All introgressionwork was performed in a greenhouse located in Memphis, Tenn. Twosubsequent backcrosses were performed and progeny were screened for thepresence of GLYTOL® and TWINLINK® Plus. Progeny homozygous fortransgenic traits were initially evaluated in 2014 in Maricopa, Ariz.for agronomic acceptance. The selected progeny were evaluated inreplicated trials in 2015 extensively across the cotton belt. In 2016, aselected component line was tested across the cotton belt and FM1953GLTP was approved for commercial release in October, 2016.

Provided herein as embodiments of the invention are seeds, plants, plantcells and parts of plants of the cotton variety FM 1953GLTP.Representative seeds of this variety will be deposited under rules 37CFR 1.801 through 1.809, prior to issuance of a patent.

Applicant does notwaive any rights granted under this patent or under the Plant VarietyProtection Act (7 U.S.C. 2321 et seq.).

Plants produced by growing such seeds are provided herein as embodimentsof the invention. Also provided herein are pollen or ovules of theseplants, as well as a cell or tissue culture of regenerable cells fromsuch plants. In another embodiment, the invention provides for a cottonplant regenerated from such cell or tissue culture, wherein theregenerated plant has the morphological and physiologicalcharacteristics of cotton cultivar FM 1953GLTP when grown in the sameenvironmental conditions. In yet another embodiment, the inventionprovides methods of testing for a plant having the morphological andphysiological characteristics of cotton cultivar FM 1953GLTP. In oneembodiment, the testing for a plant having the morphological andphysiological characteristics of cotton cultivar FM 1953GLTP isperformed in the same field, under the same conditions and in thepresence of plants of FM 1953GLTP, e.g., plants grown from the seeddeposited under Accession number XXXXXX.

In particular embodimentsof the invention, a plant is provided that comprises a single locusconversion. A single locus conversion may comprise a transgenic genewhich has been introduced by genetic transformation into the cottonvariety FM 1953GLTP or a progenitor thereof. A transgenic ornon-transgenic single locus conversion can also be introduced bybackcrossing, as is well known in the art. In certain embodiments of theinvention, the single locus conversion may comprise a dominant orrecessive allele. The locus conversion may confer potentially anydesired trait upon the plant as described herein.

Single locus conversions may be implemented by a plant breedingtechnique called backcrossing wherein essentially all of the desiredmorphological and physiological characteristics of a variety arerecovered in addition to the characteristics conferred by the singlelocus transferred into the variety via the backcrossing technique. Asingle locus may comprise one gene, or in the case of transgenic plants,one or more transgenes integrated into the host genome at a single site(locus).

In a particular aspect, the invention provides for a method ofintroducing a single locus conversion into cotton cultivar FM 1953GLTPcomprising: (a) crossing the FM 1953GLTP plants, grown from seeddeposited under Accession No. XXXXXX, with plants of another cotton linethat comprise a desired single locus to produce F1 progeny plants; (b)selecting F1 progeny plants that have the single locus to produceselected F1 progeny plants; (c) crossing the selected F1 progeny plantswith the FM 1953GLTP plants to produce first backcross progeny plants;(d) selecting for first backcross progeny plants that have the desiredsingle locus and the physiological and morphological characteristics ofcotton cultivar FM 1953GLTP as described herein (e.g., Table 1), whengrown in the same environmental conditions, to produce selected firstbackcross progeny plants; and (e) repeating steps (c) and (d) one ormore times (e.g. one, two, three, four, etc. times) in succession toproduce selected third or higher backcross progeny plants that comprisethe desired single locus and all of the physiological and morphologicalcharacteristics of cotton cultivar FM 1953GLTP as described herein(e.g., Table 1), when grown in the same environmental conditions. Plantsproduced by this method have all of the physiological and morphologicalcharacteristics of FM 1953GLTP, except for the characteristics derivedfrom the desired trait.

Another embodiment of the invention provides for a method of producingan essentially derived plant of cotton variety FM 1953GLTP comprisingintroducing a transgene conferring the desired trait into the plant,resulting in a plant with the desired trait and all of the physiologicaland morphological characteristics of cotton variety FM 1953GLTP whengrown in the same environmental conditions. In another embodiment, theinvention provides for a method of producing an essentially derivedcotton plant from FM 1953GLTP comprising genetically transforming adesired trait in regenerable cell or tissue culture from a plantproduced by the invention, resulting in an essentially derived cottonplant that retains the expression of the phenotypic characteristics ofcotton variety FM 1953GLTP, except for the characteristics changed bythe introduction of the desired trait.

Desired traits described herein include modified cotton fibercharacteristics, herbicide resistance, insect or pest resistance,disease resistance, including bacterial or fungal disease resistance,male sterility, modified carbohydrate metabolism and modified fatty acidmetabolism. Such traits and genes conferring such traits are known inthe art. See, e.g., US 20090049564, incorporated by reference herein inits entirety.

The invention also provides for methods wherein the desired trait isherbicide tolerance and the tolerance is linked to a herbicide such asglyphosate, glufosinate, sulfonylurea, dicamba, phenoxy proprionic acid,cyclohexanedione, triazine, benzonitrile, bromoxynil or imidazalinone.

In one embodiment, the desired trait is insect resistance conferred by atransgene encoding a Bacillus thuringiensis (Bt) endotoxin, a derivativethereof, or a synthetic polypeptide modeled thereon.

Also included herein is a method of producing cotton seed, comprisingthe steps of using the plant grown from seed of cotton variety FM1953GLTP, of which a representative seed sample will be deposited underAccession No. xxxxxx, as a recurrent parent in crosses with other cottonplants different from FM 1953GLTP, and harvesting the resultant cottonseed.

Another embodiment of this invention relates to seeds, plants, plantcells and parts of plants of cotton varieties that are essentiallyderived from FM 1953GLTP, being essentially the same as this inventionby expressing the unique combination of characteristics of FM 1953GLTP,including the herbicide and insect resistance of FM 1953GLTP, except forthe characteristics (e.g., one, two, three, four, or five,characteristics) being different from the characteristics of FM 1953GLTPas a result of the act of derivation.

Another embodiment of this invention is the reproduction of plants of FM1953GLTP by the method of tissue culture from any regenerable planttissue obtained from plants of this invention. Plants reproduced by thismethod express the specific combination of characteristics of thisinvention and fall within its scope. During one of the steps of thereproduction process via tissue culture, somaclonal variant plants mayoccur. These plants can be selected as being distinct from thisinvention, but still fall within the scope of this invention as beingessentially derived from this invention.

Another embodiment of the invention provides for a method of producingan inbred cotton plant derived from the cotton variety FM 1953GLTPcomprising: (a) preparing a progeny plant derived from cotton variety FM1953GLTP, a representative sample of seed of said variety having beendeposited under ATCC Accession No. PTA-XXXXXX, by crossing cottonvariety FM 1953GLTP with a cotton plant of a second variety; (b)crossing the progeny plant with itself or a second plant to produce aseed of a progeny plant of a subsequent generation; (c) growing aprogeny plant of a subsequent generation from said seed and crossing theprogeny plant of a subsequent generation with itself or a second plant;and (d) repeating steps (b) and (c) for an additional 3-10 generationswith sufficient inbreeding to produce an inbred cotton plant derivedfrom the cotton variety FM 1953GLTP.

Another embodiment of this invention is the production of a hybridvariety, comprising repeatedly crossing plants of FM 1953GLTP withplants of a different variety or varieties or with plants of anon-released line or lines. In practice, three different types of hybridvarieties may be produced (see e.g., Chapter 18, “Hybrid Varieties” inBriggs and Knowles, supra):

The “single cross hybrid” produced by two different lines, the “threeway hybrid”, produced by three different lines such that first thesingle hybrid is produced by using two out of the three lines followedby crossing this single hybrid with the third line, and the “four wayhybrid” produced by four different lines such that first two singlehybrids are produced using the lines two by two, followed by crossingthe two single hybrids so produced.

Each single, three way or four way hybrid variety so produced and usingFM 1953GLTP as one of the parent lines contains an essentialcontribution of FM 1953GLTP to the resulting hybrid variety and fallswithin the scope of this invention.

The invention also provides for cotton lint or fiber produced by theplants of the invention, plants reproduced from the invention, andplants essentially derived from the invention. The final textileproduced from the unique fiber of FM 1953GLTP also falls within thescope of this invention. The invention also provides for a method ofproducing a commodity plant product (e.g., lint, cotton seed oil)comprising obtaining a plant of the invention or a part thereof, andproducing said commodity plant product therefrom.

A        single locus may comprise one gene, or in the case of transgenic        plants, one or more transgenes integrated into the host genome        at a single site (locus).    -   Stringout Rating: also sometimes referred to as “Storm        Resistance” refers to a visual rating prior to harvest of the        relative looseness of the seed cotton held in the boll structure        on the plant. The rating values are from 1 to 5 (tight to loose        in the boll).    -   Substantially Equivalent: A characteristic that, when compared,        does not show a statistically significant difference (e.g.,        p=0.05) from the mean.    -   T1: A measure of fiber strength, grams per tex (high=stronger        fiber).    -   Tissue Culture: A composition comprising isolated cells of the        same or a different type or a collection of such cells organized        into parts of a plant.    -   Transgene: A genetic locus comprising a sequence which has been        introduced into the genome of a cotton plant by transformation.    -   Uniformity Ratio (Ur): The proportion of uniform length fibers.        The uniformity ratio is determined by dividing the 50% fiber        span length by the 2.5% fiber span length.    -   Vegetative Nodes: The number of nodes from the cotyledonary node        to the first fruiting branch on the main stem of the plant.
